APPARATUS FORTHE MANUFACTURE OF TURPENTINE ANDROSIN.

SIECIFICATION formingpart of Letters Patent No. 251,865, dated January3, 1882.

Application filed July 25, 1881.

colors the residual rosin, thereby depreciating its commercial value.Much time and labor are also spent in'dipping or strainingthe chips,&c., from the liquid rosin,and the fire risks are greatly enhanced bythe taking fire of the hot saturated chips as they are removed from thestill, mostof the conflagrations of turpentine-stills originating fromthis cause.

The object of this invention is to economize in time and labor andlessen the costs and risks in distilling turpentine; also to produce acleaner and more valuable rosin. a

Figure 1 is a sectional side elevation, showing my improved deviceapplied to a turpentine-still of improved design. Fig. 2 is a part-]y-sectional side elevation of my improved device applied to a still ofthe usual design.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the rectifier fixed within thecondensing-tank B. Said rectifier A consists of a cylindrical vessel, A,

containing a cylindrical wire screen, 0, of

nearly the diameter of the rectifier itself, and a smaller cylindricalwire screen, D, set with- Y in the larger one and supported on lugs to athat project inward from the latter. A coucave cover, E, closes the topof the rectifier A,

. and is provided with a central opening, I), for

the introduction of the crude terpentine,which opening 11 is closed,when desired, by a cap, E. Set on the floor or beams F, immediatelyabove the rectifier A, is a coarse concave screen, G, into which it isdesigned to first introduce the crude turpentine, which always containschips, pieces of bark, and other foreign substances. The screen Gretains the coarser particles of foreign substances and the Screens D Cin succession the finer particles (No model.)

thereoflit being designed that the screen 0 shall be finer than thescreen'D.

The still H is set at a convenient distance from the rectifier A and ona lower level, and the worm I from the said still H enters through aside of the tank B into the rectifier A just beneath the screen 0, andmaking several turns therein passes out into the tank B and finallythrough the side thereof near the bottom, as shown in Fig. l.

From the side of the rectifier A, near the bottom thereof, adischarge-pipe, K, conducts the strained turpentine into the still E.

It is designed that the water in the tank B shall be maintained at aboutthe level of the bottom of the screen 0, as indicated. in dotted linesat L, Fig. 1, for the purpose of facilitating the condensation of theturpentine-vapors.

With this arrangement it is found that the heat arising from thatportion of the worm I which is within the rectifier A passes through andabout the screens 0 D and liquefies the crude turpentine therein, sothat it readily flows from the foreign substances contaminating it intothe bottom of said rectifier A, and thence through the pipe K to thestill H; and at the same time the turpentine about that portion of theworm I serves by its lower temperature to facilitate the condensation ofthe turpentine-vapors.

The tank'B is provided with an orifice, 0, closed by a plug, d, on theside toward the still H, which plug dmay be withdrawn to extinguish anyfire that may. occur aboutthe said still H. This still H differs fromthe still in common use for this purpose, inasmuch as this is devoid ofthe dome, and the supply-pipe K is entered into or connected with anopening, f, in the center of the flat top of said still H, while the endof the worm I is projected down, through the top of said still H to justabove the turpentine therein. By this arrangement there is lesscondensation of the turpen tine-vapor within the still itself, andconsequently the yield of the still is very materially increased.

In Fig. 2 is shown my rectifier applied to a still, M, of the usualconstruction. 1

I am aware that crude turpentine has been freed from impurities bymelting it in a vessel having sieves therein and allowing the meltedturpentine to flow by its own gravity into the still; also that thechamber which supplies the still has been prox'ided with strainers toeliminate impurities; but

What I claim as new and of my invention 5 1. The combination of thevessel A, the cylindrical wire screens 0 D, the concave cover E, havingcentral opening, E, the superposed concave screen G, and the worm I tostrain the "[0 turpentine, as described.

2. The combination, with the condensingta-nk B and still H, of therectifier A, provided with screens 0 D and pipe K, and set within thesaid tank, and worm I, passed through said rectifier and tank,substantially as here- 15 in shown, and for the purpose described.
